Anyone else having the game crash and getting the message Civ 5 was closed by windows because of data execution prevention? I have the retail version. I installed it and ran it and got the new update from Steam. I have the correct trainer downloaded and I am able to hear trainer activated once I press F1 at menu screen. I have tried to play the game with and without choosing different settings for a game and both times when I select play, the game crashes and I get the message stated above. The game works fine without using the trainer. I tried doing what the Windows help section said to do for this problem but it didn't work. Any ideas or suggestions? Running Vista by the way.
